BOULDER - For Colorado's football coaches, there was little - make that no - downtime between the end of spring practice and the beginning of the off-field grind that will take them toward August camp.

CU concluded spring drills on Saturday night with the annual Spring Game at Folsom Field. On Sunday, all but two members of coach Jon Embree's staff - coordinators Eric Bieniemy (offense) and Greg Brown (defense) - hit the road recruiting.

Embree told several media members on Monday afternoon in a post-spring wrap-up that Bieniemy and Brown were "getting some things finished up from offensive and defensive standpoints." The entire staff will be back on campus next week, then return to the road for the month of May.

NCAA rules prohibit Embree leaving campus to recruit until Dec. 1 - "But I can make telephone calls over the next five to six weeks," he added.

CU had its Junior Day in conjunction with the Spring Game, and Embree called the event a success. There were upwards of 65 attendees, many from out of state and some with their parents, and Embree said he "expects to hear from some kids soon - a couple in particular. Seven kids that came . . . it was good they got here; they made a great effort to get here. We'll see on that."

He said his preliminary count on available scholarships for 2013 is "16 to 20."

BUFF BITS: CU's summer camps for high school players will be held July 20-22, with Embree believing those dates "allowing more kids in general to participate . . . hopefully that will be conducive for everybody." Camps for younger players (8-13) will be conducted on consecutive weekends at CU (June 1-3) and Cherry Creek High School (June 8-10) . . . . If there's any attrition on his team this summer, it should be minimal and nothing rivaling last season. "We're in the process of evaluating," Embree said, "but for the most part kids are handling their business and doing what they're supposed to do; they're giving us maximum effort on and off the field. But you know how those things go." . . . . Embree reiterated this fall's captains could be selected on a game-by-game basis. He said he "feels good about the direction of the leadership on this team," mentioning linebackers Doug Rippy and Jon Major, defensive tackle Will Pericak, quarterbacks Nick Hirschman and Connor Wood, offensive tackle David Bakhtiari, center Gus Handler, safety Ray Polk and defensive end Chidera Uzo-Diribe as players he expects to head up the Buffs' summer conditioning work . . . . Embree also said he expects receiver Paul Richardson, who underwent knee surgery Monday afternoon, to continue to function in a leadership role even though Richardson will miss the 2012 season . . . . Embree is not expecting incoming freshman quarterback Shane Dillon to redshirt. Positions where first-year players will receive early and heavy scrutiny include defensive line, defensive back, running back, receiver and tight end. Throw in return specialists, too . . . . If there are to be any fourth or fifth-year transfers, that word won't come until later this summer, Embree noted . . . . CU's uniforms won't change for 2012, but Embree said there already have been discussions with Nike for 2013. "Nothing radical," he added . . . . Embree on fans: "You can't manage fans' expectations . . . there's a lot of enthusiasm out there; it's going to be whatever it is."
